Add + buttons to create new outflows and outcomes in edit mode

Edit modal now includes:
- + button next to "Outflows" to create new funnel node
- + button next to "Outcomes" to create new outcome node
- Hover X button to remove allocations
- Auto-redistribute percentages when adding/removing
- New nodes positioned relative to current funnel

Uses useReactFlow hook to dynamically add nodes to canvas.
